Subject: [PATCH v5 02/16] clk: tegra: Don't enable PLLE HW sequencer at init
Date: Thu, 19 Nov 2020 16:53:51 +0800	[thread overview]
Message-ID: <20201119085405.556138-3-jckuo@nvidia.com> (raw)
In-Reply-To: <20201119085405.556138-1-jckuo@nvidia.com>

PLLE hardware power sequencer references PEX/SATA UPHY PLL hardware
power sequencers' output to enable/disable PLLE. PLLE hardware power
sequencer has to be enabled only after PEX/SATA UPHY PLL's sequencers
are enabled.
